Nero is one of six Baltimore police officers charged in connection with Freddie Gray's death. Nero's attorneys want the judge to ban the prosecution from claiming that Nero used excessive force, because the state never alleged that excessive force was used.

On the prosecution's side, the state is asking the judge to refuse any testimony about Gray's criminal record, prior encounters with law enforcement officers and prior hospitalizations because they said there's no evidence that Nero knew anything about Gray before his arrest, so therefore it's all irrelevant.

Nero is charged with second-degree assault, misconduct in office and reckless endangerment. As of now, Nero is the next officer to go on trial, which is tentatively set for Feb. 22.
